s/ N
rRatio be 2 (details are seen the patent " double stators and double rotors multiple-pole switching reluctance motor " of my application, application number 200910117477.7); When at three phase times, three-phase control can single hop again can two sections, every section stator poles is 3 times of rotor number of poles, promptly the rotor number of poles compares N
s/ N
rRatio be 3, thereby realized reducing to vibrate, reduced unilateral magnetic force, reduced magnetic energy loss, increased the magnetic energy area, increased the purpose that magnetic altogether can the zone with noise.
5, when two sections magnetic pole of the stator align among the present invention, two-stage rotor magnetic pole mutual deviation 1/2 rotor pole elongation, the stator alignment thereof was easy to heat radiation, reduced heat load this moment; Rotor does not line up mode and is easy to reduce rotor field phase mutual interference.
6, when two-stage rotor among the present invention aligns, two sections stator mutual deviation 1/2 stator polar angles, stator does not line up mode and is easy to reduce the mutual interference of stator field phase at this moment; The rotor alignment thereof is easy to accomplish mechanical static balance and dynamic balancing.
7, owing to adopted the relation of times utmost point, make rotor all magnetic poles in any one galvanization all do work, therefore having increased magnetic altogether can area and power usefulness.
8, in the present invention, the pole span angle that sensor signal is taken from rotor when adopting external armature to be external stator; Be fabricated to two kinds of running statuses in adopting during armature: a kind of is that outer magnetic pole maintains static and interior armature rotates, sensor signal is taken from external stator pole span angle, another kind is that interior armature is not transferred the outer magnetic pole rotation, its sensor signal is also taken from external rotor pole span angle, but interior armature is as the more suitable mechanical drive unit of internal rotor mode.
9, because control method of the present invention both can adopt the electric drive mode, also can adopt mechanical type driving apparatus, therefore can adapt to the needs of different electromechanical integration.
10, through real-world operation test, speed-regulating range width of the present invention, adjusting speed accuracy height, noise is little, vibration is little, tripping force is apart from big, and operation is changeed distance greater than existing switched reluctance machines, at generating state generating efficiency height.
11, the present invention has broken through the worldwide technological puzzle that switched reluctance machines can not permanent magnetism, makes switched reluctance machines speed governing as direct current machine, reversible generating, makes power thereby increased motor, has enlarged range of application.
